Stone Care Sealer - High Performance Emulsion Based - Type WH6973

Stone Care Sealer - High Performance Emulsion Based - Type WH6973

GRASi WH6973

GRASi® WH6973 is an emulsion-type stone protector, specifically developed to provide waterproofing for various types of stone, such as marble, granite, sandstone, and limestone.

Its nano-scale active ingredients can penetrate deeply into the substrate and bind with it, forming a penetrating protective layer on the surface. With ultra-low surface tension, it has excellent water repellency and rapid beading effects.

Features

Stronger chemical bonding, providing long-lasting protection, good durability, and stability, significantly extending the service life of building materials.
Good permeability for porous substrates, excellent wear resistance.
Prevents water vapor, moisture, and liquid water from penetrating the substrate.
One-way breathable, can repair tiny cracks (0.2 mm - 0.4 mm).
Fast curing speed, quick to use and dries rapidly.
Performs exceptionally well on natural and artificial stone.
Prevents stone loosening, cracking, peeling, and staining, easy to clean.
Good chemical resistance, such as resistance to acids, alkalis, weathering, and chloride ions, as well as good weather resistance.
Excellent freeze-thaw and high-low temperature resistance (-50℃ to 200℃).
Does not alter the original appearance of the substrate.
Environmentally friendly.

Application Instruction

GRASi® WH6973 is a ready-to-use penetrating waterproofing agent, suitable for application by spraying, brushing, or troweling.

The surface of the material must be clean and dry.
Use appropriate low pressure for spraying, at a distance of 10-15 cm.
Apply the material to the substrate until fully penetrated. For medium to high-density substrates, wipe off excess liquid with a soft cloth 5-10 minutes after application.
Do not place treated materials in humid areas or where they may be exposed to rain; allow to air dry. Subsequent treatment can be carried out once the surface is dry.
After complete curing, it will achieve excellent water-repellent effects.
The application temperature should be between 2-45℃ (35.6-113°F).
The maximum coverage per liter is 4-35 square meters, depending on the density of the stone.
